Personal Note on RAID5: as you can see here, RAID5 does need more writes compared to other RAID level. my personal opinion on RAID5 is, when you know your IO pattern from your application you can also go with RAID5 to get efficiency and same time a "good performance" when the majority of IO operations are reads and not writes. a typical scenario for RAID5 would be a.e. "Streaming Services" where mainly 100% large sequential reads does happen.
